Most of you know I am a newbie, but so far I am loving cycling and this forum. 80 miles in 2 weeks! I am doing it for weight lost but I can't help myself but try to go faster. I have set a goal of 700 miles before I buy a road bike. Is that premature? I have some friends here that do ironmen and they want to "punish me" on a road bike. Why does this make me excited?
